As a preferred embodiment according to the present invention, first, when the telephone number is to be recorded using the menu screen displayed on the CRT, the telephone number recording on the menu screen displayed on the CRT 7 (4. TELEPHONE: RECDRD ) Menu is selected as the shuttle key. Then, the telephone number recording screen as shown in FIG. 2 (b) is displayed on the CRT 7.

The telephone number recording screen shown in FIG. 2 (b) includes preset names (NAME), telephone numbers (TEL) and on-screen character information as fixed strings of character strings A to Z,-to △, 0 to 9; It consists of a blank string in which the name and telephone number are to be recorded. The fixed character strings A to (0) and 0 to 9 of the on-screen character information are character information for names and telephone numbers to be recorded in the blank string.

In addition, the fixed strings (□ to △) are function keys, where (□) indicates a clear function for one phone number recording data, and (←) and (→) designate alphabetic characters and numbers in the name and telephone number fields. To move left and right. (△) and (▽) are shift keys for moving up and down the name and phone number fields. Therefore, when you want to enter a phone number for the implementation of the present invention, by moving the cursor located on the fixed character string to the desired fixed string position by the jog key, the corresponding character set by the jog key by entering the shuttle key is the name Or a blank phone number.

On the other hand, when all of the phone number recording is finished, when you want to perform a reference to the phone number, if you select the EXIT command located at the bottom of the phone number recording screen, the phone number recording screen to the initial menu screen Will go out. At this time, the record of the telephone number mounted on the CRT 7 is stored in the storage unit 4 through the on-screen data recording and reading unit 3 while executing the EXIT command.

Therefore, the cursor is moved by the jog key to the telephone number reference (5. TELEPHONE: READ) menu position on the initial menu screen to refer to the telephone number recording data stored in the storage unit through the above process. When the set menu is selected as the shuttle key, the telephone number reference screen is displayed on the CRT 7 as shown in FIG. 2 (c).

When the telephone number reference screen is displayed on the CRT 7, the telephone number recording data stored in the storage unit 4 is read by the on-screen data recording and reading unit 3 to generate on-screen characters. The portion 5 is converted into the corresponding character and then displayed on the CRT 7 (not shown). Therefore, the user moves the phone number record screen up and down as a jog key to perform a reference to the phone number to be searched.

When all references to the telephone number are made through the above-described process, the screen is moved back to the first menu screen by selecting the EXIT command located at the bottom of the reference screen. In addition, when the first menu screen as shown in FIG. 2 (a) is to be terminated, 6. EXIT MENU is selected as the jog key and the execution of the menu screen is completed by the shuttle key.

Next, a process of performing the method according to the present invention using the OSD device having the configuration as described above will be described in detail with reference to FIG.

First, when a user inputs a menu key provided in a key input means not shown, a menu screen as shown in FIG. 2 (a) is displayed on the CRT 7 (step S1). After the phone number recording and reference menu is set by the jog key (step S2) and the preset menu is selected by the shuttle key (step S3), the menu selected by the shuttle key is displayed. It is judged whether or not it is a number recording menu or a telephone number reference menu (step S4).

As a result of the determination in step S4, if the selected menu is a phone number recording menu, the phone number recording screen as shown in FIG. 2 (b) is displayed on the CRT 7 (step S5). In such a state, when a jog key is input for creating a phone number (step S6), it is determined whether to write a name or a phone number in step S7.

In accordance with the determination in step S7, when a character corresponding to a name is to be set, the cursor is moved within a section (A to △) as a jog key (step S9), otherwise, the desired telephone number In order to create a function, the fixed character string (i) of the on-screen character information moves to the telephone number setting mode in step S8, and the cursor is moved by the jog key in the (--9) section (step S10). Then, according to the input of the shuttle key, the fixed character string of the on-screen character information set by steps S7 and S9 and steps S8 and S10 is recorded as a blank string in the telephone number recording screen, and the selected character data is stored. It is stored in the section 4 (step S11).

Then, it is determined whether the EXIT key located at the bottom of the telephone number recording screen is selected (step S12). If the EXIT key is input as a result of the determination in this step S12, the first menu for input of another telephone number is entered. The screen is converted to the screen, i.e., the process returns to the above-described step S6, and the subsequent process is repeated. Otherwise, the screen is converted to the menu screen shown in Fig. 2A for the selection of another menu (step S13).

Therefore, after performing step S13 according to the EXIT key selection in step S12, it is determined whether the first menu screen is performed or terminated in step S19. That is, if (6. EXIT MEMU) on the first menu screen is selected by the shuttle key, the menu screen on the CRT 7 is terminated, otherwise the above-described processing for setting another menu is processed. Return to step S2.

On the other hand, if the telephone number recording menu is not selected as a result of the determination in step S4 described above, it is again determined whether or not the reference menu (5. TELEPHONE: READ) for the previously stored telephone book is selected (step S14). If the telephone number reference menu is selected as a result of the determination in step S14, the telephone number recording data previously stored in the storage unit 4 is stored in the CRT 7 as shown in FIG. Is displayed on the screen.

Therefore, in the above state, the user converts the jog key value (step S15), so that the corresponding telephone number to be referred to in step S16 is displayed on the CRT continuously. At this time, by referring to each phone number (lookup) and simultaneously using the jog key and shuttle key to modify some of the recorded data for the phone number (for example, if a person's phone number is changed, change only that number) or change ( Or delete).

Then, in step S17, it is determined whether the EXIT key located at the bottom of the phone number reference screen is selected. If the mile EXIT key is not selected, a continuous reference to the phone book is made through step S15. When the EXIT key is input as a result of the determination in step S17, the screen is switched to the first menu screen (step S18).

Next, as described above, it is again judged whether or not the first menu screen has been performed or terminated (step S19). As a result of the determination in this step S19, (6. EXIT MENU) on the first menu screen is a shuttle key. When selected by the user, the menu screen on the CRT 7 is terminated, and if not, the process returns to the above-described step S2 of processing for setting another menu.

On the other hand, if the telephone number reference menu is not selected as a result of the determination in step S14, the process proceeds to step S20 to perform menu processing for the corresponding number.

As described above, the method according to the present invention can not only store a plurality of telephone numbers desired by the user in a surplus memory space in the VRC through the above-described process, but also simply refer to the stored plurality of telephone numbers. Since it can be changed or deleted, the desired telephone number can be recorded in the memory of VRC without a separate phone number recording means, thereby increasing the use of VRT.
